GALAX Xtreme Tuner Plus vs nvuv

GALAX Xtreme Tuner Plus lets users monitor and adjust GALAX graphics cards from a mobile device. It shows card temperature, frequencies, and fan speeds in real time, with controls ranging from 1-Click OC to more advanced overclocking. The app can also change fan speed and RGB effects remotely; up to 20 ARGB effects are available on specific cards with ARGB features. To link a phone or tablet with a PC, users scan a QR code in the PC app or enter the computer’s IP address. GALAX requires both devices to use the same SSID for wireless linking. The app can capture system status for sharing on social media. Android, iOS, and Windows are listed platforms, and a Windows download is provided for gaming gear support and GPU only. The iPhone app is listed at free and requires a GALAX graphics card and Xtreme Tuner PC software. GALAX says its Hong Kong company was founded in 1994 and was formerly known as Galaxytech.

nvuv is a free Linux command-line utility for adjusting NVIDIA GPU power and clock behavior. It can set power limits, lock GPU or memory clock ranges, and apply offsets to either clock. On systems with several GPUs, the `-i GPU_INDEX` option chooses the device. The project describes nvuv as a thin wrapper around NVIDIA’s NVML library. Its indirect undervolting method locks the GPU’s maximum clock and applies a positive offset because direct voltage control is not exposed on Linux. The project says this can preserve roughly similar performance while lowering voltage and power draw, with possible reductions in temperature and fan noise. Settings may come from a TOML file, using `/etc/nvuv/nvuv.toml` by default. Applying, changing, or resetting settings requires root privileges. Changes do not survive reboot, resume, or driver reload unless the supplied systemd service reapplies them. That service can run at startup and after resume or driver reload. Downloads are linked through GitHub releases and an Arch User Repository package. nvuv uses Apache License 2.0 WITH Commons-Clause-1.0.
